Triple R Composites Audi RS5 B9 Set of 6 Diffuser Fins
Give the rear of your Audi RS5 B9 a sharper, more aggressive look with this set of 6 rear diffuser fins. Designed to follow the lines of the original bumper, they add a stronger motorsport style without looking out of place.
Why choose this kit
These fins sit on the lower section of the rear bumper and help guide the air as it leaves the car. In simple terms, they help tidy the airflow and give your RS5 a more focused, track-inspired appearance.
- Custom styled for Audi RS5 B9 models from 2017 to 2019

- Nylon 12 material for strength, impact resistance and durability
- SLS 3D printed for precise shape and consistent finish

The fins are manufactured from Nylon 12 using SLS 3D printing. SLS (Selective Laser Sintering) is a method that uses a laser to fuse powdered material into a solid part. This gives a strong, accurate piece with a clean surface. After printing, the parts are media blasted to give a smooth, even texture and then coloured black for a subtle, factory-style look.
Fitment: designed specifically for Audi RS5 B9 Sportback and coupe models from 2017 to 2019. Use the vehicle lookup on our site or check the Vehicle Fitment tab for full details before ordering.
